步骤一:关闭数据库 export ORACLE_SID=bgsp 1. sqlplus / as sysdba 2. shutdown immediate 步骤二:删除实例相关文件 1. find $ORACLE_BASE/ -name $ORACLE_SID 2. 用命令删除查询后的文件 find $ORACLE_BASE/ -name $ORACLE_SID -exec rm -rf {} ; 步骤三:删除配置文件,假设我们删除的实例是YC 1. find $ORACLE_BASE/* -name ‘*[Yy][Cc]*‘ | grep -v admin | grep -v oradata 2. 用命令删除查询的文件 find $ORACLE_BASE/* -name ‘*[Yy][Cc]*‘ | grep -v admin | grep -v oradata | xargs rm -rf 步骤四:删除实例配置文件中的信息 1. vim /etc/oratab 2. 找到yc:/opt/oracle/db/product/11g:N 3. 将该行信息删除,并保存文件 经过以上步骤可以实现命令行干净的删除实例
原来这个机器上装过oracle,卸载了,选择之前安装的目录(已经删除干净了),就出现了 “[INS-32025] 所选安装与指定 Oracle 主目录中已安装的软件冲突” 的问题,解决办法为:删除C:Program Files (x86)OracleInventoryContentsXML目录下的inventory.xml 文件即可。(附带改文件内容,该目录地址在这里被占用了,所以会报错) 我是直接把oracle下面的文件都删了
